Abstract: A process for the energy efficient, environmentally friendly recovery of liquid and gaseous products from solid or semi-solid hydrocarbon resources, in particular, oil shale or tar sands. The process involves non-oxidative pyrolysis to recover fluid energy values, oxidative combustion to recover energy values as recoverable heat, and environmental sequestration of gases produced.

Abstract: A process for upgrading hydrocarbonaceous oil containing heteroatom-containing compounds where the hydrocarbonaceous oil is contacted with a solvent system that is a mixture of a major portion of a polar solvent having a dipole moment greater than about 1 debye and a minor portion of water to selectively separate the constituents of the carbonaceous oil into a heteroatom-depleted raffinate fraction and heteroatom-enriched extract fraction. The polar solvent and the water-in-solvent system are formulated at a ratio where the water is an antisolvent in an amount to inhibit solubility of heteroatom-containing compounds and the polar solvent in the raffinate, and to inhibit solubility of non-heteroatom-containing compounds in the extract. The ratio of the hydrocarbonaceous oil to the solvent system is such that a coefficient of separation is at least 50%.

Abstract: A process and apparatus for the remediation of soil is provided with a plug flow of soil and counter-current wash of water. The contaminant-containing soil with water is first treated to disengage the contaminant from the soil and form a liquid phase containing water and contaminant. The treated soil and liquid phase is continuously introduced into a wash zone at a first end of the wash zone, and the soil and the liquid phase are conveyed in successive and discrete portions through the wash zone between the first end of the wash zone and a second end of the wash zone to provide an essentially plug-flow of the soil through the wash zone.
